# Set SRCPATH and BUILDPATH to your Barrelfish source and build paths,
# respectively, and create symlinks to this file, like this:
#
# ln -s barrelfish-cc-wrapper x86_64-barrelfish-none-gcc
#
# You can set EXTRALIBS to link to libraries needed on Barrelfish that
# are not easily figured out by Autoconf or passable as LDFLAGS on the
# commandline.
